' and JOHAN POLAR, a citizen of the United States and a Belgian subject, respectively, residing, respectively, at Newport, in the county of l-lewport, State of Rhode Island, ,and'at Gleveland, in the county of Guyahoga and State or Ghio, have invented certain new and useful Improvements in Resilient Tires; and We do hereby declare the I following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same. I

This invention relates to resilient- Wheels and has particular reference to resilient Wheels which employ pneumatic tubes.

The object of "theinvention is to construct a pneumatic Wheel in. which the pneumatic tube is located bet-Ween a rim and trend element and the Wheel structure, so as to be protected by the latter, the Wheel thus presenting a compara ively nonyielding' and 'nonresisting tread and an inner air body for absorbing the shocks received by the rim.

With the above object in view and such others relating to the details of construction as Will hereinafter appear, our invention Will now be fully set forth and described reference being had to the accompanying drawings.

In the drawing Figure 1 side elevation with a portion of the Wheel structure broken znvaf-J.

Fig. 2 is a section on line 2 of Fig. 1,

Fig. 3 is a part side elevation and part sectional View, and

Fig. 4 is a detail sectional view of a portion of the inechauis i.

Referring more particularly to the drawings l and 2 represent the half sections of a wheel structure which are provided with the hub elements 3 and 4 Whose inner ends are interfittingly shouldered in order to preserve a true alinerncnl; or" their bores. The Wheel sections 1 and 2 also have the spoke Webs 5 \v ich terminate in the annular abutting ribs 6 and outside of the annular ribs are continued in the outwardly rounded channels 7 and the peripheral guil'le flanges 8. Uloviously, the Wheel sections it and "2 are identical in construction with the excep tion of the intcriitting shouldered relation of the hub elements 3 and i. and when opposed and joined by means of the bolts 9 and 10 provide continuous hub and a circular chamber between the channels 7.

ln the chamber formed of the channels 7 is a pneumatic tube 11 Whose inner peripheral face is provided with the enlarged bead 12 which is vflanged upon opposite sides to form the Wedge shaped ribs 13 which fit into correspondingly formed grooves cut into the ribs 6 of the Wheel sections. Thus,

then the heel sections are assembled to inclose the pneumatic tube, the latter is seecurely locked against movement in any di reotion by its inner peripheral structure. The outer periphery of the tube 11 is provided with substantially rectangular head which projects freely bet veen the sides of the flanges S and is provided at intervals ivith the knobs .15 upon which are seated the bearing plates 16 Whose lower faces are shaped to correspond to the cylindrical sur face of the knobs 1:") and Whose upper faces are curved to seal; against therim 17. The rini l7 consists generally speaking of an annular I-bean having its Web lying horizontally and its flanges projectedvertically to provide a seat for a tire 18 upon the outer side and to receive the bearing plates 16' upon its inner flanges; The downwardly projecting flanges oi? the rim 1? are recessed opposite the knobs 15 to form seats for the plate 16, the recesses being longer than the plate in order to permit a limited play of the latter. The head 14: of the tube 11 is furthermore provided at equally spaced in-R element and is expanded in the seat provided outer its way between the flanges 8 and the 17 in the tube containing chamber. a

The outer. faces of the flanges of the-rim 17 are provided with spherical recesses in. which are seated the balls 23, the'marginal' edges, of the openings being pinchedor.

crlmped overthe balls to hold them; in (mition. The balls project a comparatively slight distance beyond the faces of the flanges andgprovide bearings between said {aces and the inner faces of'the guide T e tube ll'is formed of heavy material,

I so as tohold'the air fora comparatively long period, and since there is no wear thereon, it is practically indestructible. The air is introduced thereto through the air connection 24 which may be projected through the Webs 6. v r

From the foregoing, it is evident that v there is provided, according to this invention, a ver strongand efiectivewheel which is well a apted for use jupoIi "automobiles and motorcycles It is impossible to pu'nc ture the pneumatic element and the relative movement between the rim 1'? and the'wheel elements 1 and 2, provide forthe absorption of all shocks given to the, tread 18. 7 It should be noted that while the relative movement between the rim 1? and the wheel ele-, ments is such as to permit the absorption of all shocks, there is a positive driving engagement between the rim and the wheel through the bearing plates 16 and the pneu matic element, so that when the wheel is used as a driving wheel there is no loss of power.

-What we claim is 1. A resilient wheel, comprising in coin- "tween the fell binatien, a pair of interfittingwheel sections including hub, felly, and spoke elements,

said felly elements forming an annular chamber therebetween, apneumatic element seated in said'chamber and having ribs locked beelements, bearing flanges formed upon t e outer edges of said wheel sectlons, a'rnn movable between said flanges and having inwardly extending flanges, bearing blocks seated upon saidpneumatic element and carrying said flanges, said iting the relative annular movement of the rim and a tread mounted uponthe p 2.
